After I remove the droppings and insulation that I can realistically remove manually, it's time to fog. There's no way to manually remove all rat droppings, and of course one cannot remove urine and fur grease. Some of the droppings are down walls. Many are basically embedded in insulation.
Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers. Through Telnet, an administrator or another user can access someone else's computer remotely.
The routers can be managed over the network by using standard TCP/IP protocols like Telnet, SSH, HTTP or HTTPS. Telnet was developed in the early days of the UNIX operating system to manage computers remotely. A Telnet client and server application ships with Cisco's IOS software and most computer operating systems.
